An injection-moulded thermoplastic mini-platform ( 42 ) is adhesively bonded, in use, to the aerofoil surfaces of a fan blade ( 312 ) in a gas turbine engine. The mini-platform ( 42 ) is divided into a number of leaves ( 46 ), to increase its flexibility, and ribs ( 48 ) beneath the leaves ( 46 ) provide additional stiffness in the radial direction. In the event that a fan blade is released in operation, the mini-platform ( 42 ) is designed to detach from the blade ( 312 ) and/or to break apart, so that damage to other components of the engine is minimised.
